Description

The invention relates to a ladder shelf system with the tools and materials for artisan Easy, safe and quick assembly and transport can be tiert.

This system consists of a cart, one in its Function changeable basic structure, at least one Hanging box. These components are in their diversity of applicable work tasks as well as in their size and coordinated in their function so that they are complement each other.

By combining the individual components of the Systems can function, store and transport Tools and materials or the use as a leader and Workbench to be met.

The basic framework serves as a shelf frame for transport of the various boxes as well as a single ladder and standing ladder.

This functional change of the basic structure ge looks over the different joints on the ladder are attached and these conductors together in their structure hold. The joints have different angles, that make it possible for the ladder to be different can be used. The ladder consists of rungs, of ladder spar, from joints, from bolts to hold a Ku gel bearings and from holding brackets. The ladder stiles are parallel arranged to each other. In between are the Sprouts that are parallel at regular intervals and right are arranged one above the other at an angle to the spars.

There is enough between the rungs Space so that even with very large shoe size and work shoes can be worked on. The rungs white a non-slip profile, which enables that even in bad weather, with greasy shoes profile or slippery ladder rungs worked on it can be. The ladder bars have a grip, whereby the ladder can also be used as a transport shelf can be set. The ladder can also be rolled up transport that are attached under a cart on the the complete ladder rack system is in place.

At both ends of the ladder there are suitcases conclusions, which are the connection of the ladder to the car chert. This ladder rack is used for various attachments boxes with their contents to be transported freely that the boxes do not touch each other and there remains intact through its content. The suspension of the Boxes are made by a ball bearing, which is held by a bolt is attached to the rungs. These boxes can be from the front and back, or the wider one Operate, remove and attach the side.

The basic scaffold ( Fig. 1) can be used as a single ladder if it is fully opened. All joints of the basic framework form an angle of 180 degrees. As a stepladder ( Fig. 12) it can be used if the outside joints form an angle of 180 degrees and the joints which are arranged in the middle are set so that the two spars of the ladder are at an angle common to step ladders .

In order to be able to use the basic framework ( Fig. 1) as a shelf frame, the outer joints must have an angle of 90 degrees. The joints in the middle form an angle of 180 degrees. The sections 1 and 4 are vertical and side by side, so that the hanging boxes have space between them.

The trolley ( Fig. 6) has two types of rollers under the bottom plate. One pair of castors can be steered in all directions and has a foot brake that is intended to secure the car against unintentional rolling away.

The other pair of rollers is only moving in one direction Lich. The wheels are on the outside under the corners of the car brought. This gives the car good driving properties. To attach the shelf frame to the trolley are on the head of luggage locks. The case locks are on the car and on the ladder on the outside. So that the trolley can be converted into a work table There are two extendable trolleys in the car Insert bolt.

These can befe by means of the insertion bolts constant knurled nuts are shifted and locked.

To reach the handles, they are attached to the trolley th smaller lid folded up. These lids sit zen on the outside of the wagon above the mecha to be protected nik of the insertion pin. If the insertion bolts are in who are retracted from the rungs of the shelf frame which she fastened with screws. The screw mentioned ben are in the ladder. These are so firmly drawn until the insert bolt is firmly in the hollow rung sits. To give the table the necessary stability under the car are two extendable telescopic legs. These legs are parallel and next to each other attached to a hinge in the opposite direction. These legs are by one at the other end Clamp spring secured against falling out. On the En they have rubber caps that scratch the floor should avoid. Then the two-part telescope leg pulled apart. You pull the thinner one Tube from the slightly thicker. If the leg is ge has the desired length, then you can use an adjustment screw the leg tight. Then the two smaller lids can be folded down again. So you get a work table that is also a cheap one Has working height. In the middle of the car is also a lid, but overall larger than that other two lids. This cover can be used as a ladder open up. To be able to open these lids easily all have a recess as thick as a glove.

There is enough space under the large lid of the car for different materials and tools.

The hanging boxes serve the content quickly and can be transported undamaged in the shelf frame.

The long sides of the box are beveled with it the boxes during transport in the rack frame in none Can touch transport position. Thus the content of the Boxes are not damaged and the box remains in the always in a horizontal position.

The hanging box is used for transport in the rack frame men hung. Located in the center of the handle a round recess that exactly the dimensions of the Ku is adjusted. These ball bearings allow that the hanging box swings freely with less Can move friction. When transporting the shelf frame unnecessary jerky bumps are avoided. The four Outside walls and the two sloping ones below Areas are on a rectangular elongated floor brought on which the most weight of the content lies. Of the Handle is so far from the narrower side that one is good can grab the hanging box by the handles to him to hang in the shelf frame. Located on the box there is a four-part lid, which contains the contents of the hinge should protect. So that when closed, nothing looks out of the hanging boxes, which the rei ensures easy transportation in the rack frame.

The lid is in four parts in total NEN of the lid two halves to the longitudinal direction of the Move the hanging box. Located on the edge of the hanging box  there is a hinge through the two cover halves can be moved. The larger part of the lid is located directly at the edge of the box. Next to it is the narrower part of the lid, in which a glove finger thick recess is incorporated. If in this Ausspa a finger is stuck in so you need to only pull the lid so that the lid opens. There at automatically the smaller lid is placed under the size outer lid which are connected to each other. By one Velcro attached to both halves of the lid remains small Stick the other lid under the larger lid. There through it is avoided that one does not unnecessarily the otherwise hanging lid is injured. Furthermore the boxes hung in the shelf frame remain free swingable. There is one on each of the handles because a hinge on which a two-part carry handle is increasing. The hinge is in the middle of the handle. This handle can be on the two long sides of the Place the hanging box. As a result, the handle also serves also as a closure for the two halves of the lid. The two Handle halves are dimensioned so that several coasts ver can be stacked non-slip on top of each other. To the The two handle halves can carry the hanging box be put together.

So that the handle ar in the two different positions can be saved at the ones indicated in the sketch Make a Velcro tape attached.
